THOMAS G. BARLOW-MASSIOKS, OF PRESCOTT, ARIZONA TERRITORY.

AMALGAMATOR FOR SEPARATING AND SAVING GOLD.

SPECIFICATION forming part of Letters Patent No. 554,902, dated February18, 1896.

Application filed January 23, 1895. serial No. 535,911. (No model.)

gravel for saving the free gold, and I employ a suitable screen in whichthe gravel is exposed to the action of water to wash out the free gold,and a pump elevates the water and auriferous materials into a tankcontaining a series of inclines or riffles with pockets at their endsinto which the gold is received and retained.

In the drawings, Figure 1 is a vertical section illustrating the presentimprovement. Fig. 2 is a sectional plan in larger size through one ofthe pockets at the line an 0c of Fig. 1. Fig. 3 is an elevation, andFig. 4 a vertical section, of one of the pockets, both figures being inmagnified size.

The rotary screen A is of any desired character, into which the gravelis received and washed by water introduced into such screen, and thewater and the materials washed out from the gravel pass into a tank 13,in which such rotary screen A is caused to revolve with the lower partof the screen below the level of the water in the tank, so as tofacilitate the washing operation.

I provide a centrifugal or other suitable pump at O for receiving thematerials from the tank B and delivering the same through the pipe Ointo a receiver D, which receiver D is in the form of a trough having anarrow opening through which the water and fine materials are dischargedevenly into a trough F within an inclosure or vessel E, such trough Fbeing at the upper part of such inclosure E. Vithin this tank or vesselE there is a series of inclines or rifiles, which may be of copperplates silver-plated, and these inclines stand in alternate directionsand they are marked G, G, G G G G G, G and G the number being more orless than those represented.

At the foot of the incline G is a pocket F, which is preferably ofcast-iron and in the form of a trough lying transversely of the vessel Eand having a vertical flange at one side by which the trough isconnected to a support, and at the other side and opposite the verticalflange the trough is provided at its upper edge with a support for thelower end of the incline G and below this with a support for the upperend of the incline G and with openings between these supports and abovethe overflow edge of the trough through which the water and finematerials flow as they pass from the incline G and are deflected by thevertical flange into the pocket F and from thence out upon the surfaceof the incline G. These supports consist of flanges projecting from theside of the pocket F for receiving and holding the lower end of theincline G and the upper end of the second incline or riffle G, and thepockets F F F F, F, F and F are made in the same manner as the pocket F,and they are placed in alternate positions at the ends of the respectiveinclines, so that the water and fine materials flow down the inclines inalternate directions, and into the pockets F F, &c. mercury orquicksilver is introduced so as to amalgamate with the fine gold andretain the same as the water and fine earthy materials flow through therespective pockets from one incline to the incline next below. Hence thefine materials being exposed to the amalgamating action in the pocketsthe gold is abstracted and retained by the quicksilver in such pockets,and little or none thereof escapes from the lowest pocket F", as thewater runs away by the door or flap H at the bottom of the vessel E.

The vessel or tank E is constructed so that when closed it will havesubstantially watertight sides and bottom, but the cover Z of the vesselE is made removable, and it is advantageous to make one side of thevessel E removable, so as to give access to all of the inclines orriffles and the pockets for introducing or removing the quicksilver andamalgam.

WVhen the tank E is closed for use the sides are substantiallywater-tight, but the flap or gate H is to be opened to a greater or lesseX- tent to allow the flow of water through said tank.

The plates or inclines G to G are to be secured at their respective endsto the pockets in any suitable manner-such, for instance, as by screwspassing through the plates into the metal flanges of the pockets.

The water running away at the door or gate H is received into a vesselland may be dis charged in any suitable 111anner-sucl1, for instance, asby the pipe K, rotary pump K and delivery pipe 01 trough K -and theremay be adjusting-screws at V for bringing the apparatus to the properlevel. This is especially advantageous when the anialgamator is placedupon a car, as is frequently done in mining, so as to move the same intoproximity to the excavating apparatus.

I claim as my invention The combination in an amalgamating ap-
